Up-and-coming audio brand EarFun is making waves in the consumer electronics market with the launch of its latest flagship product, the Air Pro 4+ earbuds. These earbuds are touted as the world’s first Hi-Res Certified dual-driver ANC earbuds priced under $100, aiming to redefine the market for budget-friendly wireless audio solutions.
The Air Pro 4+ earbuds combine Hi-Res Audio, advanced adaptive Active Noise Cancellation (ANC), and a dual-driver system, offering a premium listening experience at an accessible price point. By integrating a 10mm dynamic driver with an ultra-light balanced armature, EarFun claims these earbuds deliver “thunderous bass, crystal-clear highs, and balanced mids,” promising an audiophile-grade wireless experience.
Innovative Design and Technology
For the first time, EarFun has implemented its proprietary Nano Side-Fitted Acoustic Architecture (NSAA) in the Air Pro 4+. This design optimizes the drivers’ suspension and reduces magnetic interference. By aligning both drivers at an 11-degree angle, NSAA is said to provide cleaner resonance and a more natural treble response, all while maintaining a lightweight and comfortable fit.
A Different Angle
“Through extensive testing, we discovered that setting an 11-degree angle between the two drivers minimizes high-frequency attenuation caused by interference,” explains Rocky Deng, CTO of EarFun. “This innovation delivers clearer, more natural highs, redefining what’s possible for earbuds under $100.”
Powered by a Qualcomm QCC3091 chipset, the Air Pro 4+ offer next-generation wireless performance with support for aptX Lossless and LDAC audio codecs, thanks to the adoption of Bluetooth 6.0. A six-microphone AI-enhanced system is designed to ensure calls sound crisp and natural. Meanwhile, QuietSmart 3.0 adaptive ANC suppresses up to 50dB of ambient noise, allowing users to immerse themselves in their music without distraction.
Advanced Features and Durability
Beyond sound quality, the Air Pro 4+ earbuds incorporate the latest Bluetooth advancements such as Auracast and LE Audio connectivity. They also support Google Fast Pair with in-ear auto detection and feature an ultra-low latency Gaming Mode, ensuring audio stays in sync with on-screen action.
Up To 54 Hour Battery Life
Designed for life on the go, the Air Pro 4+ boast up to 54 hours of total battery life, or 36 hours with ANC enabled. The earbud case supports wireless charging and includes a fast-charge feature that provides three hours of playback from a ten-minute charge.
The ergonomic design of the Air Pro 4+ was informed by data from 10,000 ear models, resulting in a three-point fit that promises comfort for all-day wear. Their lightweight construction and IP55 rating ensure they are durable enough for daily commutes and sports activities.
